Abstract
PURPOSE: To increase an arithmetic processing speed by shortening a shift control time, by exercising shift cintrol by selecting a shift control pulse by a shift indication signal in a processor which performs arithmetic processing by clock pulses.
CONSTITUTION: When a shift control signal S supplied to a control terminal (a) is a 0, an AND circuit 3 is opened and a pulse signal A is supplied as an output signal C from an output terminal (b) to the shifting circuit of a processor. When the shift control signal S is a 1, namely, during shift control, an AND circuit 4 is opened, and a pulse signal B is sent out as the output signal C. Therefore, when the shift control is required, clock pulses differing in period are supplied to the processor only by sending an instruction whose prescribed bit has been changed.
